This invention haste do generally with baking machinery and, more particularly, relates "to a certain new and usefulimprovement in machines for cutting and panning biscuits.

y invention has fopit m s provision of a unitary machine'un'iquely constructed for simultaneously cutting biscuits at a high rate of speed and automaticallylfeeding:

and paths the biscuits smoothly and uniformly,

andwhich .is so constructed as to cut and pan an extremely large quantity of biscuits while utilizing the services of a single workman.

with the above and other objects in view,

my invention resides in the "novel features of form, construction, arrangement, and combina-Z 7 tion of partspresently described and pointed out intheclaims. v 1 r V In the accompanying drawings (four sheets)-' Figure 1 is a front elevational view of a biscuit" c H 25 sorbing washers 20 for stop-engagement with the a a forward lugs l1. 1
